RDL's D Series modules include a range of user controls, remote controllers, visual indicators, and connection plates. Compatible with Decora style mounting, these modules are available in a variety of colours including black, white, and silver, and are manufactured from stainless or carbon steel.

A variety of mounting plates, back-boxes and desktop mounts are available.

AUDIO INTERFACES – Bi-directional

This module has single stereo 3.5mm jack input and output to give pass-through audio with the signal path either way. Available in white (D-MJPT), black (DB-MJPT), or stainless steel (DS-MJPT). Weight: 54.4g

This panel has both 3-pin XLR input and output on the front panel, with terminal block connections on the rear of the module. Available in white (D-XLR2), black (DB- XLR2), or stainless steel (DS- XLR2). Weight: 81.6g

AUDIO SENDERS

With single, unbalanced 3.5mm jack input this active, two-pair sender is compatible with Format-A devices via RJ45 connection. The input can be connected to consumer audio equipment with a standard -10dBV level output. The signals are then amplified and routed to output cable pairs B and C. As the modules only drive two cable pairs, they can also accept both signal and power from another mic or line level Format-A sender. Format-A connection via RJ45 connectors. Available in white (D-TPS8A), black (DB-TPS8A), or stainless steel (DS-TPS8A) finishes.

LOUDSPEAKERS

This 2 watt, 8ohm, Decora-style loudspeaker has been designed to ‘produce sonic presence within an extended frequency range expected from larger speakers’. A frequency range of 150Hz to 20kHz is complimented with internal filters which ‘roll-off’ frequencies outside of the applicable range, giving for an increase in output capability and reduction of distortion. Dispersion is hemispherical and at almost 180 degrees. RDL suggest running with compatible amplifier rated up to 10W maximum. Available in white, grey, black, or stainless steel finishes. Sensitivity: 78dB, 1W, 1m. Weight: 176.9g

MICROPHONE PREAMPLIFIERS

This mic preamp provides +48V phantom power to the two balanced 3-pin XLR microphone inputs, each with switchable 40dB or 60dB input gain settings. Automatic gain can also be selected and applied to both inputs. Format-A compatible, this module drive two cable pairs and can accept both power and signal from a compatible Format-A sender at line or mic level. Available in white (D-TPSM2A), black (DB-TPSM2A), and stainless steel (DS- TPSM2A). Headroom: Over 18dB. Frequency response: 20Hz to 20kHz, +/-0.5dB. Harmonic distortion: less than 0.05%.
